Below in conjunction with accompanying drawing detailed description according to the motor 100 of the utility model embodiment and stator punching 21.
Shown in Fig. 7, comprise rotor and stator core 20 according to the motor 100 of the utility model embodiment, stator core 20 is located at the periphery of rotor, and stator core 20 and rotor are located in the housing 10 of compressor.
Stator core 20 comprises multiple stator punching 21, and stator punching 21 is the stator punching 21 according to the utility model embodiment.Multiple stator punching 21 is arranged along the axis superposition of stator punching 21.That is, as shown in Figure 1, multiple stator punching 21 is superimposed along the direction perpendicular to paper.When stator core 20 is assemblied in housing 10, the outer of stator punching 21 can be connected on the internal face of housing 10.
Each stator punching 21 comprises yoke 211 and multiple teeth portion 212 respectively, and yoke 211 is positioned at the periphery of stator 20, and yoke 211 abuts the internal face of housing 10.Multiple teeth portion 212 are located at the inner circumferential of yoke 211, and multiple teeth portion 212 is along the spaced apart setting of circumference of yoke 211.Each teeth portion 212 extending radially inwardly respectively along yoke 211, limits stator slot 213 between any two adjacent teeth portion 212.
The outer peripheral face of yoke 211 is provided with multiple breach 215, and multiple breach 215 is along the spaced apart setting of circumference of yoke 211.Multiple breach 215 can form venting channels.Yoke 211 is formed as annular, and the outer peripheral edges of yoke 211 are provided with multiple through hole 214.Each through hole 214 is spaced apart and along the through yoke 211 of axis of yoke 211 along the circumference of yoke 211.Any one through hole 214 is located between two adjacent breach 215.
According to the stator punching 21 of the utility model embodiment, by arranging breach 215 on the outer peripheral face being positioned at yoke 211, axially through through hole 214 is set on the yoke 211 being positioned at teeth portion 212 periphery simultaneously, when the edge, periphery of yoke 211 abuts the internal face of housing 10, breach 215 on yoke 211 does not contact with housing 10, the periphery of through hole 214 can closely cooperate with housing 10 simultaneously, thus the vibration that can reduce teeth portion 212 is transmitted to housing 10, guarantees the flux path of stator core 20 simultaneously.Meanwhile, stator core 20 can not because producing stress with closely cooperating of housing 10 and be out of shape, and distortion can accumulate in through hole 214 place, decreases the iron loss loss of stator core 20, and the vibration of motor 100 and noise are reduced, and the efficiency of motor 100 improves.
Particularly, stator core 20 shown in Fig. 1 assembled after situation.Through hole 214 is formed as telescopic hole, is the state after through hole 214 is out of shape shown in Fig. 1, and the dotted line on through hole 214 side is the state of through hole 214 when not being out of shape.Can obviously find out from Fig. 1, the distortion of the stator core 20 after assembling concentrates on through hole 214 place, and the inner circumferential of stator core 20 does not deform, and the cylindricity for inside diameter of stator core 20 is good.
Shown in Fig. 7, multiple through hole 214 can along the alternate setting of the circumference of yoke 211 with multiple breach 215.That is, be provided with a through hole 214 between two adjacent breach 215, and be provided with a breach 215 between adjacent two through holes 214.Thus, the part between any two adjacent breach 215 of yoke 211 all has a through hole 214, effectively prevent stator core 20 stress and deform, decrease the iron loss loss of stator core 20, the vibration of motor 100 and noise are reduced, and the efficiency of motor 100 improves greatly.
The shape of through hole 214 can be formed as multiple, and such as, as shown in Figures 2 and 3, in embodiments more of the present utility model, each through hole 214 can be formed as multiple circular ports of the spaced apart setting of multiple circumferences along yoke 211 respectively.When the periphery of yoke 211 and the internal face of housing 10 closely cooperate, multiple circular port can deform.
Further, in the embodiment shown in fig. 3, stator punching 21 is provided with the through hole 214 be made up of multiple circular port, and stator punching 21 also comprises groove 216.Groove 216 runs through yoke 211 along the axis of yoke 211.Groove 216 comprises multiple, multiple groove 216 respectively on the spaced apart outer peripheral face being located at yoke 211 and each groove 216 lay respectively between two adjacent circular ports.It should be noted that at this, each groove 216 lays respectively at and refers in the circumferential direction along yoke 211 between two adjacent circular ports, and each groove 216 is roughly located between two circular ports being adjacent.
As shown in Figure 3, form protuberance between adjacent two grooves 216, the extended line of the center of circle of circular port between adjacent two grooves 216 and the imaginary line in the center of circle of yoke 211 divides equally the protuberance between these adjacent two grooves.Thus, at yoke 211 in the radial direction, protuberance is corresponding with circular port.When the periphery of yoke 211 and the internal face of housing 10 closely cooperate, protuberance is stressed to internal strain, and deflection is passed to corresponding circular port, ensure that the cylindricity for inside diameter of stator punching 21.
